G-Rad Posted September 26, 2013 Report Share Posted September 26, 2013 My cousin has a Jensen Head unit, flip up style, and for some random reason, the other day he said his door speakers quit working altogether, however his subwoofers still play music. The car is a 2007 Ford Focus. His door speakers have never been on an amp. The radio still has power, like I said, the subwoofers still play, and they're tied into an amp from the back of the unit. Any ideas what could be causing this at random? Please let me know. Thank you.

Dan2427 Posted September 26, 2013 Report Share Posted September 26, 2013 False I had all mine cut out when I had a bad speaker. The surround came unglued and shorted out and at higher volumes they would cut out til I turned it back down. 2003 GMC Yukon Denali Alpine CDA 117 Redoing Mids/Highs 4 Runs of 1/0 Knukonceptz 2+, 2- 4 Deka 9A31's in back (Stock underhood) 250 amp Alt.

rockFord_Expedition Posted September 27, 2013 Report Share Posted September 27, 2013 Is the sub amp fed a low level or high level signal? If low level, the H.U. Internal amp could be bad. Was it sudden? And did he check his connections? Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire Link to comment Share on other sites More sharing options...
G-Rad Posted September 27, 2013 Author Report Share Posted September 27, 2013 The sub is fed a low level input from the unit. We also hooked up another stereo and got the same results. I am believing it has to be somewhere in the speakers, but how would one speaker shorting out cause the whole system to go down? It doesn't even produce any signal when I restart the radio or anything... I tried a CD, I tried a station. antennae was plugged in nad I got the exact same results. I can assure there's no stock amplifiers. We've even hooked tweeters straight up to the radio harness and it didn't work on either stereo either. *shrugs* BASS MEKANIK RECORDS "Audio Implosion" & "SubSonic Guillotine" available anywhere digital music is sold! 2007 Ford Focus (NOTE: My cousin's build I helped him with) Pioneer H/U (4) Absolute Dome Tweeters on A & C pillars Scosche HD683A's in front doors Fosgate R168x2's in rear doors SoundQubed HDS312 in custom 2.57 Ft^3 @ 30Hz Audiopipe APCL-1800.1D Q-Mat Audio Technix 0 Gauge 119aH/850CCA Marine Deep Cycle batteries YouTube Channel: http://www.youtube.com/DWRhythm Link to comment Share on other sites More sharing options...

G-Rad Posted September 28, 2013 Author Report Share Posted September 28, 2013 There is no electrical tape. It's all solder and shrink tube. Right now it's just the stock door speakers and the subwoofer amplifier and still just the subwoofer is the only thing making any noise. I'm stumped. I wouldn't think there'd be some kind of fuse somewhere though. My cousin wants to believe that's the case but what would the fuse do for speakers? Something is just not adding up somewhere.

n8ball2013 Posted September 28, 2013 Report Share Posted September 28, 2013 Im not sure what part you are missing you have a short on a speaker lead or a bad speaker. Take a known good speaker disconnect everything in the vehicle. and test each channel on that known good speaker individually. If you still get no sound you have a smoked internal amp on the head unit. you may have to connect a speaker with the head unit off and then try each channel. Thats it Its either a bad speaker a grounded out shorted wire or a bad head unit amp.
